Test Conditions
Note
1:
Input voltages may exceed the supply voltages, provided the input current is limited to ±100
A.
2:
Dissipation rating assumes device is mounted with all leads soldered to printed circuit board.
3:
Refer to “Differential Input” discussion.
4:
Backplane drive is in phase with segment drive for “OFF” segment, 180° out of phase for “ON” segment.
Frequency is 20 times conversion rate. Average DC component is less than 50mV.
